(Node.js) ETrade OAuth1 Authorization (3-legged) Step 1

Demonstrates the first step in 3-legged OAuth1 authorization for the ETrade REST API. This example sends an HTTP request to the "request token URL" to get a request token that begins the OAuth1 process. (See https://developer.etrade.com/ctnt/dev-portal/getDetail?contentUri=V0_Documentation-AuthorizationAPI-GetRequestToken )

This example uses the sandbox request token URL. The live request token URL would be "https://etws.etrade.com/oauth/request_token".

Note: Requires Chilkat v9.5.0.64 or later.
